SPECIFICATION forming part of Letters Patent No. 787,261, dated April11, 1905.

Application filed October 17, 1904. Serial No. 228,704.

To r/// Il'/I///)I it may won/c0711..-

Be it known that I, "ILLIAM S. BARTON, of ()rangtdnu'g, in the county ofOrangeburg and State of South Carolina, have invented certain new anduseful Improvements in Strzuldle-Row Cultivators; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The primary object of this invention is to provide a straddle-rowcultivator having in terchangeable sweeps for throwing more or lessdirt, according to the height of the plants.

A further object is to so construct and arrange the parts as to permit ahorse to walk at one side of the growing crops while thecultivator-sweeps will work at both sides of a single row and the groundbetween the rows will be cultivated.

A further object is to permit of the ready changing of the cultivatorinto a rake by the removal of the sweeps and the insertion ofrake-teeth. and a still further object is to provide a cultivator of thecharacter specified which will be composed of but few parts, simple andinexpensive, and not liable to readily get out of order.

The invention will be hereinafter fully set forth, and particularlypointed out in the claims.

in the accmnpanying drawings, Figure l is a view in perspective. Fig. 2is a plan view. Figs. 3 and i show the two sweeps in their twopositions. Fig. 5 is a detached view in perspective of one of thesweep-blades.

Referring to the drawings, 1 designates the beam, and 2 2 the handles,secured to the rear end thereof. 3 designates a tooth-carrying baradjustably secured to the under side of beam 1 by a clip 4, said barbeing set at an angle to the line of draft as well as to the beam. Itsposition may be readily adjusted by loosening the nuts of the clip andthen tightening the same after the bar has been placed at the desiredangle.

5 designates a brace connecting the toothor cotton or other plants.

to conform to the position of the tooth-carrying bar 3.

7 designates rake-teeth mounted on bar 3, one of such teeth forming theconnection between such bar and the brace-bar These rake-teeth arepreferably removably held by nuts screwed on the threaded ends projectedthrough openings in the bar.

8 S designate two sweeps arranged approximately parallel and designed towork the ground on opposite sides of a row of corn The standards ofthese sweeps are preferably formed with upper rightangled ends El,equipped with spaced-apart parallel checks to accommodate the brace-bar,such cheeks having openings to receive nutted bolts l 0. To permit thesestandards to be placed the desired distances apart, the nuts of bolts 10are loosened and the standards are moved along the bracebar to thedesired extent. Each of the sweepstandards carries at its lower end apeculiarlyformed shovel or blade 13 for raising and sweeping the soilagainst the growing plants. Each shovel is formed with two lateral wingsH 15, the former being narrower than carrying bar to the beam at a pointin rear of clip 4, such brace being itself held to the beam by a clip (5to permit of its adjustment the latter and designed for light work,while the wider is intended for heavy work. If it is necessary to coverthe roots with but little dirt, the wings 14 are caused to face the row,while if much earth is needed the wider wings 15 are placed inopposition to each other. To do this, it is only necessary tointerchange the two sweep-standards. By reference to Fig. 2 it will beseen that the two sweep-stamlards are located to one side of the beam,and being designed to straddle the row a horse attached to the forwardend of the beam will walk to the left of the row being cultivated. Fromthis figure it will also be seen that by reason of the angularity of thetooth-carrying bar to the line of draft the two sets of rake-teeth willwork the ground between adjacent rows.

The brace-bar serves not only to retain the tooth-carrying bar in itsvarious positions, but also forms a support for the sweep-standards. Thelatter may be placed as far apart or as close together as conditions mayrequire, such ad ustments being necessitated by the conditions of thecrops undergoing cultivation; Furthermore, the brace adds materially tothe strength of the cultivator and allows the tooth-carrying bar to beadjusted to any desired extent. To efiect a change of positions, it isonly necessary to loosen the clips and retighten them after thetoothcarrying bar and brace-bar have been ad justed.

When the implement is not in use as a cultivator, it can be quicklychanged into a rake by removing the sweep-standards and substitutingadditional rake-teeth 7.

The advantages of my invention are apparent to those skilled in the art.

I claim as my invention 1. A straddle-row cultivator having standards,and blades or shovels carried by said standards having each a narrow anda wide lateral cutting-wing, said standards being removable andinterchangeable to arrange i toward each other the corresponding wingsof adjacent blades, for the purpose stated.

2. A straddle-row cultivator comprising a beam, a tooth-carrying baradjustably se cured thereto and set at an angle to the line of draft,rake-teeth depending from said bar at or near the ends thereof, a bracesecured to said bar and to said beam, and sweepstandards depending fromsaid brace for working on opposite sides of a row, said standards havingshovels or blades formed with wings for cutting to different depths.

3. The combination with the beam, the bar adjustably secured thereto,and raketeeth secured to said bar, of a brace adjustably secured to saidbeam and to said bar, one of said teeth forming the connection betweensaid brace and said bar, and blades or shovels carried by said brace.

4. The combination with the beam, the bar adjustably secured theretohaving the greater portion of its length at one side of said beam andrearwardly disposed with relation thereto, and rake-teeth secured tosaid bar, of a brace adjustably secured to said beam and therearwardly-extending por tion of said bar, and blades or shovels carriedby said brace.

5. The combination with the beam, of a bar pivotally secured to saidbeam having the greater portion of its length at one side of said beam,a series of rake-teeth depending from said bar at one side of said beam,a second series of rake-teeth depending from said bar at the oppositeside of said beam, a space being provided intermediate said secondseries of rake-teeth and said beam, a brace pivotally secured to saidbeam and to said bar, and blades or shovels depending from said brace inline with the space intermediate said second series of rake-teeth andsaid beam.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

WILLIAM S. BARTON.
